I am just geting started with cows. I just received a Jursey (4 days old) and a Housettn that is 2 days old. They both have REAL runny stools. I have been feding them 2 times a day like I was told. I am feeding them the Purina Milk Replacer. How much should I be feeding them? What can I do about their stool problem? It seems to be getting worse each time I feed them.
